OWNER ANSWER
Why does my BYD DOLPHIN roof blind only move while I hold the button?
If the panoramic roof blind still moves smoothly while you hold its button, try the DOLPHIN’s sunshade initialisation. Use the close button in the overhead panel. The procedure is for the fabric blind on the DOLPHIN with the matching roof controls.
- While parked, check that the blind moves smoothly when you hold the overhead close button, marked ② in the handbook diagram. Keep hands and objects clear of the moving blind.
- Hold the close button until the blind reaches its fully closed position. Release it when you hear the motor stop at the end of travel, as described in the DOLPHIN handbook.
- Tap and release Open, then test Close the same way. A brief touch should move the blind automatically. Either button can stop it partway.
What success looks like
The blind moves after you let go of the button and stops at the end of its travel or when you tap a button again.
If that did not work
If the blind jams, makes a grinding noise before it is fully closed, or still only moves while you hold the button after initialisation, stop repeating the procedure. Tell BYD whether the blind moves normally when held and where it stops or makes noise. Ask them to check the blind mechanism and its end-position learning.
